3 Care of patients with endocrine system disorders Introduction The endocrine system is a network of glands that produce and release hormones that help control many important body functions, especially the body's ability to change calories into energy that powers cells and organs. Common endocrine disorders are; - Diabetes ( type 1 or type 2) - Thyroid disorder ( hyperthyroidism or hypothyroidism ) 1. Blood Glucose monitoring A ) Blood glucose and monitoring Blood glucose is the amount of glucose in the blood (mmol/l). Blood glucose is regulated by insulin and glucagon. Blood monitoring (BM) is used to indicate when blood glucose is not within the normal range (4-7mmol/L) ( mg/dl). It is used to monitor and manage the treatment of both insulin-dependent diabetes mellitus (IDDM) and non-insulin dependent diabetes mellitus (NIDDM). B ) Goals for BGM The Goal: To maintain blood glucose within target range. Immediate benefit: Identification, treatment, and prevention of high and low blood glucose levels. Long-term benefit: Decrease risk of long-term complications. C) Who s client need to measure BG (Indications) type 1 and type 2 diabetic patients. unstable diabetes, (hyperglycemia, hypoglycemia, and diabetic ketoacidosis). To make a diagnosis of diabetes indicated by signs and symptoms of polyuria, polydipsia, weight loss of type 1 or weight gain, family history of type 2. Patients taking steroids and other drugs that cause raised blood glucose. 2

4 D) Contraindications; Some conditions affect the accuracy of blood glucose monitoring (need a venous sample) : 1. Peripheral circulatory failure and severe dehydration e.g., diabetic ketoacidosis, shock, hypotension. These conditions cause peripheral shutdown, which can cause artificially low capillary readings. 2. Some renal dialysis treatments. 3. Hyperlipidemia: cholesterol levels above 13 mmol/l may lead to artificially raised capillary blood glucose readings 4. Pre-eclampsia E) Equipment; Blood glucose monitor Patient record book disposable test strips Disposable lancets Quality control solution Gauze swabs disposable gloves Sharps container cleaning wipes F) Steps;. 1) Reviews doctors orders and identifies individual. 2) Washes hands and applies gloves, uses clean technique for procedure. 3) Gathers equipment/supplies and explain procedure to the patient. 4) Cleanses site to be tested (fingertip) Do not use alcohol gel. Also, Sites should be rotated if testing is frequent to reduce risk of infection and prevent areas from toughening. 5) Turns on glucometer by inserting testing strip. 6) Properly uses lancet and injects site. 7) While holding individual s finger, allows sip-in of blood on testing strip. 8) Wipes site while applying pressure with a clean dry tissue until bleeding stops, then disposes of lancet into biohazard container. 9) Reads results and documents on MAR. 3

6 G) Role of nurse; 1) Check BG as order 2) Document results 3) Give medication or glucose (insulin\oral diabetic drug) 4) Communicate blood glucose results to physician according to policy. 5

7 2. Insulin administration A) Insulin types; Rapid-acting - Humalog, Novolog Short-acting - Regular Intermediate - Lente, NPH Long-acting - Ultralente, Glargine (Lantus) B) Delivery Methods; Insulin Syringe Insulin Pump Insulin Pen 6

8 C) Route: Subcutaneous D) When to Give Insulin; Before meals or snacks. For blood glucose levels significantly above target range. Insulin dose depending upon; Blood glucose readings, Age/body weight, Physical activity level. 7

9 3. Radioactive Iodine Uptake A) Radioactive Iodine Uptake Test; Radioactive iodine uptake test is a type of nuclear test performed to evaluate thyroid function. The test measures the amount of radioactive iodine (taken by mouth) that accumulates or absorbs in the thyroid gland. The patient ingests radioactive iodine capsules or liquid. After a time (usually 6 and 24-hours later), a gamma probe is placed over the thyroid gland to measure the amount of radioactivity in the thyroid gland. Normal Results - 6 hours: 3 16% - 24 hours: 8-25% The test takes about 30 minutes. B) indication; Find the cause of an overactive thyroid gland (hyperthyroidism). Plan treatment for hyperthyroidism. Plan treatment for patients who have had thyroid cancer surgery C) Contraindication; allergic to any medicines, such as iodine any test using radioactive materials or iodine dye, such as a CT scan, 4 weeks before the RAIU test pregnancy. breast feeding. 8

10 D) Patient Instructions after test; flush the toilet twice each time use (2days) wash hands thoroughly after each time of urinate. Sleep alone. Avoid kissing and hug for 5 days. Wash clothing separately. E) What abnormal results mean; Normal Results - 6 hours: 3 16% - 24 hours: 8-25% Increased (greater than 35% at 24 hours is considered elevated): 1. hyperthyroidism 2. goiter Decreased: 1. hypothyroidism 2. subacute thyroiditis 9

11 4. Medications Insulin Class & uses Action Side effect Nursing role C: Antidiabetic pancreatic hormone U: type 1&2 diabetes, gestational DM Decrease BG by transport of glucose into cells and conversion of glucose to glycogen Blurred vision, dry mouth, rash, flushing, hypoglycemia, anaphylaxis, warmth. Assess: fasting BG, A1c test. S&S of hypo-hyperglycmia Evaluate: normal BG level, no S&S of hypo-hyperglycmia Glucophage metformin Class & uses Action Side effect Nursing role C: Antidiabetic U: type 2 diabetes Inhibits hepatic glucose production and increases sensitivity of peripheral tissue to S&S of hypohyperglycmia Weakness dizziness agitation, lactic acidosis, hypoglycemia, heart burn, diarrhea, thrombocytopenia decreased B12 level Assess: hypoglycemia, CBC, liver and renal function, lactic acidosis Evaluate: normal BG level, no S&S of hypo-hyperglycmia Thyroxin Class & uses Action Side effect Nursing role C: thyroid hormone U: hypothyroidism, and thyroid cancer replaces or provides thyroid hormone, controlling both development and maturation. It also controls metabolism in adult organisms. Increased sweating, sensitivity to heat, mental/mood changes (such as nervousness, mood swings), tiredness, diarrhea, shaking (tremor), headache, shortness of breath. Assess: thyroid gland hormone. Administration: on empty stomach for at least 1 hr. Evaluation: no S&s of the side effects, hormone at normal level 10

12 To summarize : Common endocrine disorders are; - Diabetes ( type 1 or type 2) - Thyroid disorder ( hyperthyroidism or hypothyroidism ) Diabetes can be controlled by ant diabetic drug such as Insulin that administer subcutaneously through injections or pen or insulin pump. Thyroid disorders such as hyperthyroidism or hypothyroidism can be tested by Radioactive Iodine Uptake Test and treated administer thyroid hormone 11
